FIELD: arrangements for obstructing or restricting traffic, particularly to protect hinged gates against rapidly moving vehicles. SUBSTANCE: device comprises support pivotally connected with fastening means, which secures device to gate leafs. Device in accordance with the first embodiment comprises beam hinged to support, wheel movably connected to beam and resilient member secured to beam by one end. Device in accordance with the second embodiment comprises slide moving along support, wheel movably connected to slide and resilient member fastened to slide by the first end thereof. Another end of resilient member is secured to fastening unit or to support. Resilient member may be made as curvilinear beam or spring. In the second embodiment resilient member made as spring may be put on support. EFFECT: provision of gate movement stoppage in the case of vehicle impingement upon gates.
The invention relates to the field of security, and particularly to protective devices for swing gates and doors, and can be used as anti-terrorism measures on the administrative, military and civil purposes. At the present time, the majority of terrorist acts against buildings and constructions administrative, military and civil purposes, is accomplished by penetration of the territory of interest vehicles filled with explosives, and later there undermining Grozny, December 2002; Znamenskaya, may 2003; Mozdok, August 2003; Magas, September 2003; Baghdad, October 2003, December 2003; Tikrit, February 2005 and so on). Most vulnerable to the penetration entrances are equipped, as a rule, gates and or gates. Existing methods of countering such threats are hardening gates and barriers, the installation of concrete blocks, pull-out racks and stakes etc. (Shapoval O. L., Motkin Century A. Application protivotumanki devices (PTU) on road and rail transport. "Cesis NIKIRET", Penza, - <URL:http://www.cesis.ru/rooVcatalog/publ/PU_2>), where a review of the comparative technical characteristics protivotumanki devices, which may be regarded as analogues. It is shown industrial products as analogs can add and technical solutions protected by patents (see table 1).
However, application of these methods and devices have the following disadvantages. Barriers (PT-4, PT-6, RU2224840) prevent the movement of vehicles, but not Hiking persons, and therefore are, as a rule, as a Supplement to the gate. Installation of the barrier takes time to install racks barrier in the soil. Installing the rising cylinder (City 275) requires a lot of time and work in excavation (digging trenches, cylinders, trenches for electrical and mechanical drives). Blockers (RSB70, PJU) require little installation time on the road surface, but down have a low bandwidth that may adversely affect, for example, when emergency evacuation or fire events. Gate (AU2003268602) require time and labor for the installation of guide rails, on which the door slides aside. Trap (US4576509) requires more labor for digging with dimensions exceeding the dimensions of the vehicles. The above-mentioned disadvantages accompanied by the high cost of such devices, and the high cost of their installation and operation. Therefore, the preferred may be technical solutions that not only does not impede the passage, but now it turns out the have the stopping effect on fast moving vehicles. A well-known way to counter the opening swing gates and doors (hereinafter - gate) is a method, when the gates are propped up by inclined palm-fringed backwaters (bars, rods, pipes and the like) suitable length, the other end of which rests on the road surface (floor). When using a skid when you try to open the sash hinged gate or door coupling apparatus with a horizontal surface is even stronger, what is stopping the action. The disadvantage of this method is the necessity of securing the clutch props as the door of the gate, and the road surface (floors), that, for example, can be provided by creation of additional stops on the surfaces of the gate and the coating, which greatly hinders the normal operation of the gate. One of the technical solutions that facilitate operation of the gate, equipped with palm-fringed backwaters, is a swivel support with a gate (Cuckow A. Emphasis gates // Behind the wheel, 2000. No. 5, P.172), which can be considered as a prototype. Its disadvantage is the necessity of fixing the props in the position in which it does not touch the floor when you open and close the gate. In this regard, is the technical problem of providing as stopping action of the gate with a RAM (vehicles traveling at high speed, so besprepjatstvenno opening gates and doors during normal operation. The problem is solved with a device that uses inertia to podporu, when normal operation is not related to the road surface (floor), to bring into contact with this surface and thus provide a stop for the door and gate with a RAM (vehicles traveling at high speed. The invention disclosed in the specific examples of its implementation with reference to the accompanying drawings, which depict the following : Figure 1 is a kinematic diagram protivotumanki device in the first embodiment in a static position. Figure 2 - the same, in the switched position. Figure 3 is a kinematic diagram protivotumanki device according to the second variant in a static position. Figure 4 - the same, in the switched position. 5 is a graph of the relative deformation of the elastic element over time for large and small initial velocities gate leaves. The proposed device in the first embodiment (figure 1, figure 2) consists of a support 1, beam 2, pivotally connected with the support 1, the wheels 3, movably mounted on the beam, the elastic element 4, one end of which is fixed either on the mount 5, or backwater, and the other end fixed to the beam 2, and pivotally connected with the staff of the mount 5 is intended for mounting everything on the device Assembly to shut the gate (figure 1, 2 gate is shown by the dashed line). The proposed device according to the second variant (figure 3, figure 4) consists of a support 1 on which the elastic element 4 and the slider 6, able to move through the backwater, the slide 6 is movable fixed wheel 3 and the mount 5 is designed for mounting the entire device Assembly to shut the gate (figure 3, 4 gate is shown by the dashed line). The technical result is achieved due to the fact that protivotumanki device in both versions is composed of the elastic element 4, which is in a static condition (figure 1, figure 3) and in the steady state of motion does not allow backwater to come into contact with the road surface (floors), but in the beginning of the movement with a speed above a certain threshold (figure 2, figure 4) due to the inertia of the elements of the device of the elastic element is deformed and backwater comes in contact with the road surface (floor). Upon further movement of the gate leaves backwater lower end cut into the road surface and is buried in it, preventing opening of the gate leaves. In the first embodiment, the device (1) with the deformation of the elastic element 4 beam 2 rejects podporu 1 to position (figure 2), in which there is contact support 1 and the road surface (floor). In the second embodiment of the device (Phi is .3) with the deformation of the elastic element 4 prop 1 is shifted relative to the slider 6 to the position (figure 4), when the contact support 1 and the road surface (floor). In both cases, the elastic element may be in the form of either a curved beam or spring. The process of operation can be illustrated by the time-dependent deformation of the elastic element (figure 5). Since the movement of the gate or door with the speed υ0the center of the wheel begins forward motion with an initial velocity equal to zero and represents a damped oscillatory motion relative to the movement of the gate or door. Moreover, the greater the initial velocity, the greater the amplitude of these oscillations. When the value of the initial speed greater than a certain limit, the deformation becomes larger values of xthe operated(the shaded area in figure 5), in which there is contact support with the road surface (floor). The operation of the device will be closed and bolted the gate, and gate, sborki which are not closed, and only opened or open only partially. When the vehicle speed 40 km/h (11.1 m/s) and the amount of deformation of the positives about 20...40 cm response time offer protivotumanki device will be about 0,02 0,04...C. 1.
